CA3000 delay

I recently installed an intermatic CA3000 switch in a home, in this configuration;

3000 >>> 3-way switch (jumpered) >>>light

The circuit seems to work normally, except for when the CA3000 is pressed, there is about a 10-30 second delay almost every time. There is no delay when using the 3-way switch.
The CA3000 is not yet included on a network.

A coworker told me had experienced this problem, while the switch was included, but either the switch itself or the vera corrected the problem.

Any help?
